First of all I want to clarify that I do not speak English and I am using a translator. Sorry if something fails to understand.

When I have to choose someone as a couple this occurs. Click the scroll arrows does not work. I can not choose the option "no partner" and if I click on "combat" the game stops working. It also happens that my strongest peers are enabled to be chosen and I can use them, but the scroll arrows are still not working.
